Colostrum is the first milk a cow produces after it gives birth. All mammals make colostrum as the "first milk". Yup, human mommies too! 

Also known as "liquid gold", colostrum is a super special dairy item.

It's not only important for newborn health. It also has some amazing gut healing and immune boosting properties for older mammals, too. Because of this, some people choose to take colostrum as a supplement or give it to their furry family. 

But, gee, there are a bunch of colostrum options out there! And each has its own pluses and minuses and dosing recommendations. And, when it comes to raw liquid colostrum, there isn't much info out there at all. 

So, I made this resource for you that answers these questions. I hope it helps you make the best choice for you when it comes to food and natural healing đŸ™ Here we go!

What is colostrum?

Colostrum is the first liquid a mammal produces within the first 4 days after it gives birth. You can think of it like it's a super charged milk. A mammalian body produces colostrum for good reason: It's essential for optimal newborn health. 

Compared to milk:

  • Colostrum is usually thicker and more yellow.
  • Colostrum is filled with immunoglobins to boost a baby's immune system, like 5,000%+ more. This helps protect young ones from illness. 
  • Colostrum has lots of growth factors, at least 2x more. This helps a newborn develop a strong and healthy gut.
  • Colostrum has 2-5x as much protein. First colostrum can have up to 15% protein!
  • Colostrum generally has more vitamins. Most notably, it has at least 47x more Vitamin E and 2x more Vitamins D and B2.
  • Colostrum generally has more minerals, most notably it has 4x more zinc.
  • Colostrum has more fat, at least 66% more.
  • Colostrum at least half the amount of sugar (AKA lactose). This makes it generally easier to digest.

Can see why colostrum can be called "super charged"?

What's in colostrum that makes it a healing food?

I could get super science-y here. But, I'll do my best to keep it simple.

Antimicrobials = Enhanced Immunity and Gut Health

Colostrum is packed with immunoglobins (AKA IgG antibodies) and other immune-boosting constituents like oligosaccharides, lactoperoxidase, lysozyme, and lactoferrin. Working synergistically, they help protect the body against foreign invaders like bacteria, viruses, and allergens. 

Getting these via colostrum can help your body learn what to do and enhance the function of your immune system! Once your body knows what to do, it can more easily do the same thing the next time. They can also help restore balance in your gut, helping keep the numbers of "bad bacteria" in check.

Did you know that humans pass this antimicrobial goodness to their babies via the placenta? Cows don't do that! And that's why cow colostrum is specifically and seriously packed with antimocrobials.

Immune regulators = Help Fight Infections and Restore Balance 

Colostrum contains immune regulators like cytokines and leukocytes. These can help prevent, treat, and even destroy harmful bacterias and viruses. 

Gut issues are typically fraught with an overpopulation of bad microbiology and an underpopulation of the good microbiology. Removing the bad stuff can immediately reduce inflammation. And creating better balance can allow for gut healing,

Growth Factors = Promote Healing and New Growth

Colostrum contains so many kinds of growth factors, from the common peptides to things that can fall into categories like glutamine, nucleotides, and polyamines to super important insulin-like growth factors, too.

Growth factors do exactly what they sound like they do - they encourage growth. So let's say your gut lining is damaged (or really anything in your body is damaged), colostrum can help it rebuild more quickly.

What's the difference between powdered and liquid colostrum?

Liquid colostrum is simply straight colostrum. It's milked from a cow and either consumed immediately or frozen for later use. It's the purest, most bioavailable, and most potent form of colostrum. All of the healing powers are intact.

Powdered colostrum (and the capsules and tablets made from it) started as frozen liquid colostrum. Then, it's generally pasteurized and freeze dried. Now both of those processes can reduce, inhibit, or destroy certain healing properties of colostrum. In short, the less processing, the more healing powers.

Plus, with powdered colostrum, the final product may be altered from its original composition. For example, it might have the fat removed, or maybe they put additives in there for anti-caking, preservation, etc. This can negatively affect the synergistic healing qualities of colostrum.

With liquid colostrum, is there nutritional loss with freezing?

The longer colostrum is frozen, the more probiotic loss. For this reason, I don't recommend freezing colostrum for more than 3-6 months. I mean, it will still have some good stuff in it. But why waste those amazing healing properties?

If choosing liquid colostrum, how much should I take as a supplement?

First things first, if you're new to dairy, especially raw dairy, take it slow! You definitely don't want to shock your body, especially when you're trying to heal something. Take a teaspoon, and see how you feel over the next few days. Then slowly up the dose and reduce the timing until you find a regimen that works best for you.

You can't OD on colostrum. On the other hand, a little bit goes a long way. Most people taking colostrum as a supplement use about 1-2 oz per day. It's like a daily shot of liquid gold.

What's the difference between first milking and second/third milking colostrum?

Well, it's just like it sounds. 

First milking colostrum is from the first milking after a cow gives birth. It's the most potent and contains the most healing properties.

Second/third milking colostrum is from the second and third milkings after a cow gives birth. It's not as potent but still has great healing powers. You can always take more second/third colostrum to get the same benefits as first.

It's also important to note that this is not an exact science. Every batch of colostrum will vary. Why? Every cow/calf combo is different. Plus, the time between birth and milking will vary. I mean, we won't know if a cow gives birth at midnight, so we can't go out there and immediately milk her on a special schedule.

What about the calves? Do they get any colostrum?

Of course! We know how important it is for optimal health, so the calves always get first dibs on colostrum. We take whatever is leftover, whatever they don't drink from their mom.

Our colostrum inventory is always limited.

This is the nature of colostrum. We can't just make more now. We need to wait for a cow to give birth. It always in and out of stock, sometimes for shorter on longer periods of time.

And, if you ask when it's coming back, we may not have a direct answer. This is because we don't know the exact day cows give birth (that's nature's decision). And probably more importantly, the calf always gets first dibs. We never know how much will be left for us (sometimes there's none).

The bottom line is that you've got to get our colostrum when it's available.

Is colostrum part of your life? Powder or liquid? If yes, what benefits have you seen?

What’s really in a grocery store turkey?

It’s that time of year again—the turkey takes center stage. Whether it’s Thanksgiving, Christmas, or just a Sunday family dinner, a golden-brown bird is often the star of the show. But if you’re grabbing a conventional turkey from the grocery store, you might be wondering: what’s actually in it besides turkey? Why not add weird stuff to our holiday dinner? Many conventional turkeys are “enhanced” before they even make it to the freezer aisle. That usually means they’ve been injected with a solution of water, salt, and sometimes sugar or broth. It’s meant to keep the meat "moist and flavorful", but it also means your turkey may contain up to 15% of stuff that isn’t turkey. Always check the fine print on the label—you might be paying turkey prices for salty water. I sure hope you like your turkey with a side of salt! Those injections can leave a grocery store turkey surprisingly high in sodium. And when you see “natural flavorings” or “seasonings” on the label, it isn’t always just herbs and spices—it can also mean more hidden salt and flavor enhancers. So what exactly are these “boosters”? Think modified food starch for texture, “natural flavorings,” caramel coloring, and sometimes even MSG for that extra hit of savory flavor.Here’s the kicker: take a look at this turkey below—it’s sold by a major brand and proudly labeled ALL NATURAL. But read closely, and you’ll see it actually contains about 4% “other ingredients” that aren’t clearly listed. Makes you wonder, right? Turns out the real stuffing happens long before Thanksgiving—it’s all corn, soy, and unnatural junk. Conventional turkeys are typically raised on large farms where antibiotics may be used to prevent illness in crowded conditions. The USDA regulates withdrawal periods before processing (meaning the birds shouldn’t have antibiotics in their system at slaughter). So does that mean the birds really aren't antibiotic free after all? How confusing for the consumer! As for what the conventional turkeys are fed: Grains:Corn, wheat, and barley aren’t just wholesome-sounding grains—they’re the cheapest way to pack calories into a turkey, fueling rapid growth. Efficiency, not nutrition, is the goal here.Seed Oils:Soy, canola, and flaxseed are tossed in, not out of kindness, but to boost fat content and keep growth on track. Soy especially dominates, since it’s cheap and plentiful—most of it genetically modified. So these turkeys are definitely not low PUFA.Protein sources:Turkeys grow fast, and that means they need protein—lots of it. Beyond soy, feed mills mix in other plant-based proteins to supercharge growth in young poults. The formula isn’t about balance or natural diets; it’s about pushing birds to market weight as quickly as possible. Seed oils, sugar and more, OH MY! Certain “self-basting” turkeys may also contain a touch of sugar or dextrose, oils, or even phosphates to help retain moisture during roasting. My gosh this list keeps going on and on... And the star of the show... Conventional turkeys are genetically bred to grow quickly and large, especially in the breast area—because that’s what most shoppers want. It’s something Big Ag has down to a science: decades of selective breeding for size and speed at the expense of health and flavor. The result? A bird designed for profit margins, not taste. Compared to wild or heritage turkeys, today’s supermarket turkeys are bland, bloated, and bred to fit industry demand, not the dinner table. These turkeys don’t look much like wild turkeys anymore. So what's in a Miller's turkey that makes them so darn special? ✔ Pasture Raised✔ Corn & Soy Free✔ Traditional "White" Breed - Has nice sized breasts✔ Washed in Water and Only Water✔ Nothing Added - No artificial flavors, no colors, no synthetic ingredients, no preservatives✔ Vaccine, Chemical, Antibiotic, Drug, and GMO FreeWondering what's in our turkey feed?

Does exploding milk kefir mean it's bad? Not necessarily.

We get this question from customers on the regular --> "My kefir exploded. Is that normal? Does that mean it's bad?" The answer? Bubbly volcanic kefir is 100% ok. Kefir is known as the "champagne of dairy" for a reason! In case you haven't tried it, milk kefir is a fermented drink made with milk. It's similar in taste to yogurt (a little stronger in my opinion) but has more probiotics.  As I've heard it said, yogurt is good for cleansing the gut. Kefir, on the other hand, adds to the gut. People working to heal or enhance the function of their digestive system often turn to kefir as part of this process. Even though kefir has been around for thousands of years, it seems that there's still some mystery around it. I mean, it's just not as popular as yogurt, particularly in the US. Bubbles in kefir are a natural part of the fermentation process. To make kefir, you need to add culture to milk. Different from yogurt culture, which is strains of probiotic bacteria only, kefir is a symbiotic culture of probiotic bacteria AND yeast.  Once the culture is added, you let it ferment at room temp. The culture eats up the milk sugar (AKA lactose), creates bubbles (AKA CO2), and grows more of the culture. When you get bubbly kefir, that's a sure sign that it's fermented. It's also a sure sign that it's probiotic. After all, the more CO2, the more eating and duplicating the bacteria and yeast did. After we make it, kefir will continue to ferment. It will happen more rapidly at room temp and more slowly in the fridge. But, it's still happening. More and more bubbles are created over time. And, if that container is air tight, lots of pressure builds up within the container. If you don't open the kefir and it's super fermented, there is the potential for lots of bubbles upon opening. Here's a short video of a kefir explosion: And, here's a little story about the worst kefir explosion I've heard of. Years ago, we used to sell blueberry kefir. With that added sugary fruit in the end, the culture would really take off. A customer sent us a picture of blueberry kefir on her kitchen ceiling!! It really exploded. I wish I could have been there to help her clean it up! Open slowly or burp kefir to stop it from exploding. Not a fan of your kefir exploding? Thankfully, there's an easy solution. Open slowly. Simply crack the lid a little, and let the gas escape before opening all the way. You could even burp your kefir every day or two in the fridge to prevent it from getting too bubbly. The only way to stop kefir from fermenting and creating more bubbles is to freeze it. However, I don't recommend that.  First off, kefir tends to get clumpy when thawed.  Second, there's some probiotic loss when freezing. The longer it's frozen, the more probiotic loss. If you need to freeze kefir for later, I don't recommend freezing it for more than 3 months. You know kefir really went bad by the smell and look. When you make kefir with raw milk, it's slowly turning into kefir cheese. So when I say it goes "bad", it's really just knowing when it's too sour or pungent to palate. It's not necessarily a safety issue. Here are two things to look for: Putrid Smell: OK, kefir smells funky, even good kefir. But, especially if you've been drinking kefir for a while, you should be able to tell when it smells putrid. Like, you absolutely aren't able to consume it.Massive Separation: A little separation in kefir is normal. You will see the whey (a yellowish liquid) separate from the thicker white part. But, if it's all separated, and the white creamy part has turned into a mass of clumps, it's probably not the best to consume anymore. *Side note: I think this is why most kefir comes in a container that's NOT clear. When you make kefir with pasteurized milk, it's a different story. Since there isn't a natural community of microorganisms that are regulating themselves, it has the potential to go bad in a dangerous way. In addition to the signs listed above, here's one more thing to look for: Visible Mold: Especially green, orange, red, or black mold, which is a clear indication that the kefir is bad and should be tossed. All in all, this is really about trusting your gut and being connected to your food. How bubbly has your kefir been? Have you ever had it explode? Do you drink kefir for its yumminess or probiotic benefits? I'd love to hear from you. Comment below to share your thoughts with our community (no account required).

Top 3 reasons why grass fed raw milk changes in flavor and consistency.

Have you ever noticed that the flavor and consistency of our raw milk varies from week to week and especially season to season? This is 100% normal! You see, when you raise animals naturally on pasture (and especially when they're 100% grass fed like our cows and buffalos), the milk changes. This is starkly different from pasteurized milk you'd find in stores, which is usually from grain fed cows in feedlots. With that level of unnatural control, the milk can be consistent (or maybe I should call it boring). Here are the top 3 reasons grass fed raw milk varies: 1- Butterfat changes with the seasons. It's highest in the colder months. From the anecdotal experience of myself and our farmers, butterfat is highest in the spring. That's when milk is the creamiest, the most yellow, and the most flavorful (after all, fat holds the color and the flavor). That's when you get a hefty creamline in your jug of milk after sitting in the fridge for a few days. But then... I found an interesting study on this. It's from 1931, before dairy farming got seriously messed up. It tracked hundreds of cows over many years. The researchers found that butterfat and outdoor temperature have an inverse relationship. And they found that it didn't really matter when the cows give birth and the age of the cow. Fascinating! In short, the higher the temp outside, the less butterfat. The lower the temp outside, the more butterfat. Check it out: Another interesting note on the graph is they found that Jersey cows produce milk with the highest butterfat. We noticed this, too, and it's why Aaron's herds are 80% Jersey and 20% Jersey crosses. That's why our milk is so darn creamy! It does make me wonder why, anecdotally, we feel butterfat is highest in spring. Maybe it's because our cows produce the most milk in the spring and least in the winter...? We feel like we're swimming in butterfat in the spring. We make sooo much butter at that time of year. 2- Flavor changes with the feed. When the forage, the weather, and the seasons change, so does the flavor. When cows are outside on pasture, eating a diversity of plants, the flavor of the milk they produce is more robust. Mostly this is a good thing. In my opinion, our pastured milk is more flavorful and tastes better than conventional grain-fed feedlot milk. But, sometimes this can kick us in the butt. For example, when a cow finds a little patch of onion grass, that can create an odd flavor in the milk. The weather affects what the cows are grazing on, too. For example, when we're in a drought, the grass doesn't grow as voraciously. It's has less moisture and protein and isn't as fully developed. That can change the flavor of the milk.  And finally, there are, of course, the seasons. When the cows are eating fresh pasture in the warmer months, the milk will have a different flavor than when they're eating dry pasture (AKA hay) in the colder months. It's hard to predict what the final flavor will be. But, I sure do love tasting the differences in milk throughout the year! 3- How long it lasts changes with cleanliness. Clean milk lasts longer! Milk safety is a top priority here at Miller's. Our strict milk safety standards go beyond what's required for a raw milk permit in Pennsylvania. We test every batch on site for general bacteria counts. Not many raw milk farmers do that, but we sure hope more hop on board! Since we test every batch, we're able to keep a close eye on how well the team is cleaning. Even a small thing like a cat licking equipment in the barn, a tiny hairline crack somewhere, or water not being hot enough can make a big difference.  Because of our constant monitoring, we're pretty confident in saying that our milk is the cleanest around. There's no manure in our milk!  And because of this, our milk lasts longer than most. It's raw milk and will sour (no way to prevent that). But, it should last at least 2 weeks after you receive it before it becomes too sour to palate. Do you value milk consistency over naturalness? Have you noticed changes in our raw milk over time? What about milk makes it "the best" for you? I'd love to hear from you. Comment below to share your thoughts with our community (no account requred). Or, contact us to keep it private 😊 PS: Did you know that we make our fresh raw cow dairy in house? That's right. Our team does it in our creamery! Our goat and buffalo farmers make their own fresh raw dairy in house, too. ----- Sources THE INFLUENCE OF ENVIRONMENTAL TEMPERA- TURE ON THE PERCENTAGE OF BUTTER FAT IN COW'S MILK*
